Specification of Letters Patent.

Patented Aug. 31, 1915.

Application filed October 16-, 1913. Serial No. 795,490.

To all whom it may concern.

Be it known that 1, CHARLES A. SWAN- soN, a citizen of the United States, residing at Earlville, in the county of La Salle and State of Illinois, have invented certain new and useful Improvements in Roof-Valleys, of which the following is a specification.

This invention relates to roof constructions, and more particularly to the valley or gutter formed by two oppositely sloping portions of a roof, and the object of the invention is to provide a novel and improved roof valley which is perfectly water-tight and which is so constructed that any water which may seep under the roofing shingles runs 01f instead of soaking into the shingles.

In order that the invention may be better understood, reference is had to the accompanying drawing, in which Figure l is a cross section of the valley, and Fig. 2 is a plan view of the sheet metal member which covers the valley.

Referring specifically to the drawing 5 denotes the roof timbers which meet at an angle, as shown in Fig. 1, to formthe valley or gutter. In the angle of the roof timbers is mounted a sheet metal strip or plate 6 bent longitudinally at the middle to conform to the angle. The strip has corrugations 7 which run from the longitudinal edges toward the center of the strip, at an oblique angle to the length of the strip, as clearly shown in Fig. 1. The inclination of the corruguations is in the direction of the slope of the valley. The roofing shingles 8 cover only the corrugated portions of the strip, leaving the remaining middle portion of the strip exposed.

By providing the strip 6 with the corrugations 7 any water which seeps under the shingles 8 is allowed to run down into the valley formed by the middle portion of the strip, the corrugations carrying the water into the valley. Thus the water is prevented from soaking into the shingles and rot ting the same, and eventually causing a leak in the roof.

It will be noted that the length of the corthe strip.

rugations is such that if a straight line is drawn from the inner end of a corrugation toward the longitudinal edge of the strip from which said corrugation extends, perpendicular to said edge, said line will intersect an adjacent corrugation. In other words, the corrugations overlap, thereby forming an effective barrier throughout the entire length of the strip against water passing over the edges thereof.

It will also be noted that the corrugations are tapered in width in the direction of the longitudinal center line of the strip, the corrugations being widest at the longitudinal edges of the strip, where they come close together, so that the strip, along its edges, is undulatory, as clearly shown in Fig. 2. By giving the strip this shape along its longitudinal edges, together with the overlapping arrangement of the corrugations hereinbefore described, the Water is effectually prevented from passing over the edges of The device may also be used as a flashing where two walls or a roof meet at an angle, or where a slanting roof meets a wall.

I claim:

A roof valley comprising a metal strip bent along its longitudinal median line into angular cross-section, and having corrugations running from its longitudinal edges toward the center at an oblique angle to the length of the strip, the length of the corrugations being such that the inner end of each corrugation overlaps an adjacent corrugation, said corrugations being tapered in width in the direction of the longitudinal centerline of the strip, the widest portions of the corrugations being at the longitudinal edges of the strip, and coming close together thercat, whereby the strip is given an undulatory form along said edges.

In testimony whereof I aflix my signature in presence of two witnesses.
